Maintain a Healthy Lawn With an Aerator

Compacted soil prevents grass from getting the sunlight, water and nutrients it needs to thrive. That’s why an aerator is a valuable tool for your yard. A spike lawn aerator loosens soil and fights excessive thatch buildup. It also helps boost grass seed growth. That means the grass roots can penetrate more deeply into the soil, leading to a fuller, healthier lawn. Breaking up soil also helps prevent rainwater puddles, erosion and runoff, and lawn disease. Check out our guide — How to Aerate Lawns to Grow Grass Fast — for more information.


Lawn aerators come in a range of styles, from spiked aerator sandals to automatic, 15-inch electric aerators. The key to deciding which aerator best suits your needs is to think about the size of your lawn. For small lawns and grassy areas, a manual push lawn aerator is a cost-effective, low-maintenance option. For larger lawns and for shoppers who already own a riding mower or lawn tractor, a tow-behind grass aerator is the most effective choice.


Frequently Asked Questions

Q: How often should you aerate your lawn?

A: In areas with heavy or dense soil where there is high foot traffic, aerate every six to 12 months to help prevent compaction. If you have lighter, more sandy soil, every two to three years should work well.


Q: Should you spike your lawn?

A: Yes, it’s good to spike your lawn. To decide when to spike your lawn, consider the type of grass you have. For cool-season grasses, it’s best to aerate your lawn in early spring or early fall. For warm-season grasses, late spring to early summer is best.
